IMPROVEMENT IN STEAM COOKING AND WASHING APPARATUS.

Specification forming part of Letters Patent No. 162,033, dated April13, 1875; application filed February 18, 1875.

To all whom it may concern Be it known that I, WILLIAM COOPER, ofYpsilanti, in the county of Washtenaw and in the State of Michigan, haveinvented certain new and useful Improvements in Steam Cooking andWashing Apparatus; and do hereby declare that the following is a full,clear, and exact description thereof, reference being bad totheaccompauying drawings and to the letters of reference marked thereon,making a part of this specification.

The nature of my invention consists in the construction and arrangementof the several parts of a steam cooking and washing apparatus, thepeculiarities of which will be hereinafter more fully set forth.

In .the annexed drawings, making part of this specification, bothfigures, 1 and 2, are vertical sections, but on different lines.

In the figures, A represents the base of the machine. B represents theash-pit, and O the fire-chamber. This fire-chamber is inclosed within aboiler, F, but has an outlet through the pipe D. E represents a door inthis pipe, which communicates with the fire chamber, and through whichfire is introduced. Both the fire-chamber and the boiler are conical inshape.

In the top of the boiler F is a pipe, G, which communicates with avessel or apartment, J, which forms the upper portion of the apparatus.This vessel is used for the steaming of clothes, or vegetables, orwhatever may be placed in it.

When it is to be used for steaming and cleansing clothes, aconical-shaped pipe, M, is titted overthe pipe G, as seen in Fig. 1.This pipe M is closed at its upper end, but near this end a series ofsmall tubes, 12 n, are inserted with their mouths opening downward. Theclothes are placed upon a perforated diaphragm, K, which is supportedupon ribs in the bottom of vessel J. WVhen the water becomes hot andsteam is generated, both the steam and water pass up from the boilerthrough pipes G and H, and through the tubes 12 n, and are injected uponand into the clothes. The cleansing of the clothes is effected then asin all steamers and washers of this class.

When vegetables or food is to be steamed, the pipe M is removed, thediaphragm raised and secured at any suitable height in the vessel J, andthe steam allowed to pass in through pipe G. A cover or lid, 0, isfirst, however, placed upon the vessel.

When I desire to heat water outside of the boiler, or to steam food foranimals, I use a pipe, H, which is made of uniform diameter, as seen inFig. 2. This pipe is closed at its upper end, but has an elastic pipe ora suitable pliable hose connected to it, as seen, by means of whichsteam may be conducted to any heater or tank when water is to be heatedor food steamed. The pipe H is fitted over pipe G, of course, asrepresented.

While the process of steaming and washing clothing is being carried on,the water which would otherwise be all carried out from the boiler isallowed to pass down again from the vessel J into the boiler by means ofa pipe, 0. This pipe at connects to the boiler near its bottom, and thenpasses or connects to the vessel J near its bottom, so that neitherwater or steam will pass up through it, but water will pass down.

The boiler is emptied of water through a small stop-cock pipe, P, whichis located near its bottom. The hosepipe may be connected to this, andthe water thus conveyed away to any desirable place.

It will be seen that both the fire-box and the boiler are flaring inshapethat is, in the shape of truncated cones inverted.

By this construction I get more heat and heating-surface than I couldotherwise in the same space.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The combination of the boiler F and its pipe G, as arranged with thefire-chamber O, and the pipe D with feed-door E, all constructed as andfor the purpose specified.

2. The pipe H, as constructed, and the hose L, in combination with thepipe G of the boiler, as and for the purpose set forth.

3. The combination, with the boiler F, fire chamber 0, pipe D, and pipeG, of the vessel J, perforated removable diaphragm K, and the removablepipe M, having downward-projecting tubes n, and the connecting-pipe a,all constructed substantially as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of February, 1875.

WM. COOPER.
